To study the regeneration effects of electric acupuncture on the sciatic nerve injury.Methods: The retrograde tracing of HRP was used on sciatic nerve injured rats. Results: The count of labelling cell in anterior horn of spinal cord and spinal ganglion of L4 and L5 in electric acupuncture group ranks first. There is a significant difference comparing with that of model control group. The count of labelling cell in traditional Chinese medicine group ranks secondly. And Western medicine group ranks thirdly. Conclusions: Electric acupuncture therapy improved the connections among peripheral nerves and central nerves

is one effective method in quickening nerve regeneration and improving nervous function.
